General information about product categories and U.S. FDA rules, not medical advice and not guidance for any individual patient or procedure.
Short answer
“Used medical supplies” covers three different things: unused surplus stock (overstock, closeout or liquidation lots), single-use devices that a reprocessor has cleaned and re-validated, and reusable equipment that has been serviced or remanufactured. In the United States, FDA treats each differently, so the first question for any lot is which of the three it is.
Definition and scope
The phrase is trade shorthand, not a regulatory category. FDA does not define “used medical supplies”; it regulates specific activities: reprocessing single-use devices, and servicing or remanufacturing reusable devices. This guide sorts the common trade terms into those activities so a buyer can tell which rules and documents apply. It covers U.S. rules only and does not cover donation, which has its own page: donating unused medical supplies.
Surplus, overstock, closeout and liquidation
In trade usage these words describe why stock is being sold (excess quantity, discontinued line, a business winding down), not the condition of the product. Such stock may be entirely unused. The terms are not defined in FDA rules, so they tell a buyer nothing about labeling, sterility or expiry on their own. For the inventory side of this, see deadstock and obsolete medical supply inventory.
Reprocessed single-use devices
FDA describes a single-use device as one intended for one use, or on a single patient during a single procedure (Federal Food, Drug, and Cosmetic Act section 201(ll)(1)). A reprocessed device is one that has been cleaned, disinfected and, where required, sterilized for another use. See medical device reprocessing for the reprocessing process itself.
Serviced and remanufactured reusable equipment
FDA’s May 2024 final guidance on remanufacturing separates servicing (repair or routine maintenance to return a device to the original manufacturer’s specifications and intended use) from remanufacturing (any activity under 21 CFR 820.3(w) that significantly changes a finished device’s intended use, performance specifications or safety specifications). Words such as refurbished, reconditioned or rebuilt are marketing labels; FDA looks at the activity performed rather than the entity’s self-identified designation.
How the three kinds work in practice
The FDA rules that attach to each kind are different, and so is the evidence a seller should be able to show.
- Unused stock: the product is the original manufacturer’s, so the original label, unique device identifier (UDI) and lot or expiry information are what identify it.
- Reprocessed single-use devices: under section 510(o), a reprocessor of a Class I or II single-use device must submit a premarket notification with validation data (cleaning, disinfection, sterilization where required, and functional performance) for a specified maximum number of reprocessings. For Class III devices a premarket report is required. Third-party and hospital reprocessors are treated as manufacturers subject to the requirements that apply to original manufacturers.
- Serviced or remanufactured equipment: servicing returns a device to the original manufacturer’s specifications, while remanufacturing significantly changes intended use or performance or safety specifications. FDA’s guidance applies to reusable devices; reprocessed single-use devices are handled under the reprocessing rules above.
Comparison: what to check for each kind
| Kind of “used” | FDA rule that applies | What to look for on the label or in the paperwork |
|---|---|---|
| Unused surplus, overstock, closeout or liquidation stock | Original labeling (21 CFR 801) and UDI (21 CFR 830) requirements of the manufacturer | Original manufacturer label; UDI with device identifier and, where present, lot or batch number and expiration date |
| Reprocessed single-use device | Section 510(o) premarket submission; section 502(v) labeling; reprocessor subject to 21 CFR 801, 803, 806, 820 and 830 | The statement “Reprocessed device for single use. Reprocessed by [the person or establishment responsible for reprocessing].” A reprocessed device without it is misbranded |
| Serviced reusable equipment | FDA servicing definition: return to original specifications and intended use | A record of what repair or maintenance was done and against which original-manufacturer specifications |
| Remanufactured reusable equipment | 21 CFR 820.3(w); the remanufacturer carries manufacturer obligations | Identification of the remanufacturer and the activity performed that changed performance or safety specifications |
Where it matters for supply decisions
FDA’s UDI system gives a practical check that works on any lot. The UDI has a device identifier, a fixed portion identifying the labeler and the version or model, and a production identifier, a variable portion that can carry the lot or batch number, the serial number and the expiration date of a specific device. The device identifier can be searched in AccessGUDID, which is searchable by device name, company or identifier, so a buyer can confirm that the label on a lot matches a registered device record. For the label items to confirm on large orders, see bulk medical supplies buying guide.
For equipment, the sorting question is the activity: ask the seller to say whether the work was servicing or remanufacturing, and by whom. FDA states that not all single-use devices are suitable for reprocessing, so “reprocessed” is not a general substitute for “new” for every product. Dealer categories for lab instruments are covered in used lab equipment dealers, and acceptance paperwork in donated equipment acceptance documentation.
Common misunderstandings
Is reprocessed the same as used?
No. A reprocessed single-use device has been through a validated cleaning and sterilization process by a reprocessor that FDA regulates like a manufacturer, and it must carry the section 502(v) statement. A device that was simply used and resold with no such process is not covered by that pathway.
Does “refurbished” mean FDA-cleared?
Not by itself. FDA looks at the activity performed, not the label a seller chooses. Servicing and remanufacturing are different activities with different consequences.
Does unused mean safe to use?
Unused stock keeps whatever expiration date and lot information the manufacturer assigned. Those details live in the UDI production identifier, so check them on the label rather than relying on the seller’s description.
FAQ
What do surplus, overstock, closeout and liquidation mean?
They are trade terms for why stock is being sold, not for its condition. None is an FDA category, so they say nothing about labeling, sterility or expiry.
What must a reprocessed single-use device be labeled with?
The section 502(v) statement: “Reprocessed device for single use. Reprocessed by [the person or establishment responsible for reprocessing].” Without it the device is misbranded (FDA, content current as of 08/01/2024).
Where can a device identifier be looked up?
In FDA’s AccessGUDID database, by device name, company or device identifier.
